MySQL is an open-source relational database system. Replication is a process that replicates data from a MySQL database server (master server) to another server (slave server slave.Configure the master server)1. Edit the database configuration file my. cnf, which is usually in the/etc/directory.1. # vi/etc/my. cnfAdd the following code under [mysqld:1. log-bin =

MyIsam is relatively simple to publish, just copy all the files in the library. The procedure of copying Innodb is similar to that of MyIsam, except that the table content in the Innodb Engine no longer exists in the same database directory (MyIsam does this). In the Innodb engine, data files are stored in files such as ibdata1, and operation logs are stored in files such as ib_logfile0, ib_logfile1, and ib_logfile2 by default.Innodb replication and p

data inconsistency, we had to reverse the original master-slave relationship and re-build the replication environment, and use the original master as the slave to provide external read services. Re-building the replication environment will bring us a lot of extra work. If there is no proper backup, it may make the replication
